WARNING
Read all instructions before using the appliance.
To reduce the risk of fire in the oven cavity:
a. Do not overcook food.
b. Remove wire twist-ties from paper or plastic bags before placing bag in the oven.
c. Do not heat oil or fat for deep frying. The temperature of the oil cannot be controlled.
d. Look at the oven from time to time when food is heated in disposable containers made of plastic,
paper or other combustible materials for signs of smoke or burning.
e. If materials inside the oven should ignite, or smoke is observed, keep oven door closed, turn oven
off, and disconnect the power cord, or shut off power at the fuse or circuit breaker panel.
To reduce the risk of explosion and sudden boiling:
a, Do not place sealed containers in the oven. Babies bottles fitted with a screw cap or teat are
considered to be sealed containers.
b, When boiling liquids in the oven, use a wide-mouthed container and stand about 20 seconds at the
end of cooking to avoid delayed eruptive boiling of liquids.
This oven is for food preparation only and should only be used for heating, cooking and defrosting food and
beverage.
It is not suitable for industrial, laboratory use, or heating therapeutic devices eg. Wheat bags.
Never operate the oven whilst any object is caught or jammed between the door and the oven.
Do not try to adjust or repair the oven yourself because of hazard. The oven must be adjusted or repaired
by a qualified service technician trained by SHARP.
Do not operate the oven if it is not working correctly or damaged until it has been repaired by a qualified service
technician trained by SHARP. It is particularly important that the oven door closes properly and that there
is no damage to:
(1) Door (warped), (2) Hinges and Latches (broken or loosened), (3) Door Seals, Sealing Surfaces and oven
cavity (buckled or deformed), (4) Burn marks on the door seal faces.
Do not bump, or catch utensils, loose clothes and your accessories on the door safety latches when removing
food from the oven.
Never poke an object, particularly a metal object, through a grille or between the door and the oven while the
oven operating.
Never tamper with or deactivate the door safety latches.
Always use oven gloves to prevent burns when handling utensils that are in contact with hot food. Enough
heat from the food can transfer through utensils to cause skin burns.
Should the supply cord become damaged, it must be replaced with a special cord supplied by a SERVICE
CENTRE APPROVED BY SHARP. And it must be replaced by a qualified service technician trained by
SHARP.
Avoid steam burns by directing steam away from the face and hands.
Slowly lift the furthest edge of a dish's cover and microwave plastic wrap and carefully open popcorn and oven
cooking bags away from the face.
Make sure that the power supply cord is undamaged, and that it does not run under the oven or over any hot
surfaces or sharp edges.
Do not use the oven near the steamer and fryer.
Do not place anything on the outer cabinet.
This appliance must be earthed.
Do not store food or any other items inside the oven.
Make sure the utensil does not touch the interior walls during cooking.
Only allow children to use the oven without supervision when adequate instructions have been given so that
the child is able to use the oven in a safe way and understands the hazards of improper use.
This appliance is not intended for use by young children or infirm persons without supervision.
Young children should be supervised to ensure that they do not play with the appliance.
Individuals with PACEMAKERS should check with their doctor or the manufacturer of the pacemaker for
precautions regarding microwave ovens.

SPECIAL NOTES
DO DON’T
Eggs, fruits,
nuts, seeds
vegetables,
sausages and
oysters
Popcorn
Baby food
General
* Puncture egg yolks and whites and
oysters before cooking to prevent
"explosion".
* Pierce skins of potatoes, apples,
squash, hot dogs, sausages and
oysters so that steam escapes.
* Use specially bagged popcorn for the
microwave oven.
* Listen while popping corn for the
popping to slow to 1-2 seconds.
* Transfer baby food to small dish and
heat carefully, stirring often. Check for
suitable temperature to prevent burns.
* Remove the screw cap and teat
before warming baby bottles. After
warming shake thoroughly. Check for
suitable temperature.
* Food with filling should be cut after
heating, to release steam and avoid
burns.
* Stir liquids briskly before and after
cooking for even heating.
* Use a deep bowl when cooking liquids
or cereals to prevent boiling over.
* For boiling or cooking liquids see
WARNING on page 2.
* Cook eggs in shells. This prevents
"explosion", which may damage the
oven or injure yourself.
* Reheat whole eggs.
* Overcook oysters.
* Dry nuts or seeds in shells.
* Pop popcorn in regular brown bags or
glass bowls.
* Exceed maximum time on popcorn
package.
* Heat disposable bottles.
* Overheat baby bottles.
Only heat until warm.
* Heat bottles with nipples on.
* Heat baby food in original jars.
* Heat or cook in closed glass jars or air
tight containers.
* Deep fat fry.
* Heat or dry wood, herbs, wet papers,
clothes or flowers.
* Operate the oven without a load (i.e. an
absorbing material such as food or wa-
ter) in the oven cavity.
Canned foods
Sausage rolls,
Pies, Christmas
pudding
Meats
Utensils
Aluminium foil
Browning dish
* Remove food from can.
* These foods have high sugar and/or
fat contents.
* Cook for the recommended time.
* Use a microwave proof roasting rack
to collect drained juices.
* Check the utensils are suitable for
MICROWAVE cooking before you use
them.
* Use to shield food to prevent over
cooking.
* Watch for sparking. Reduce foil or
keep clear of cavity walls.
* Place a suitable insulator such as
microwave and heat proof dinner plate
between the ceramic shelf and the
browning dish.
* Heat or cook food while in cans.
* Overcook as they may catch fire.
* Place meat directly on the ceramic
shelf for cooking.
* Use metal utensils for MICROWAVE
cooking. Metal reflects microwave
energy and may cause an electrical
discharge known as arcing.
* Use too much.
* Shield food close to cavity walls.
Sparking can damage the cavity.
* Exceed the preheating time recom-
mended by the manufacturer. Exces-
sive preheating can damage internal
parts of the oven.
